Schematic workflow for untargeted urinary volatilome methodology. The workflow steps include: 1)Â Urine pretreatment, including collection and storage conditions, and matrix modifications to enhance the extraction of the volatile compounds; 2)Â Analytical conditions, including the selection and tuning of several parameters from extraction parameters, sample incubation, and analytical instrumentation; 3)Â Data analysis including normalization and identification sources. 4) Urine volatilome obtained after combining results of the 34 studies analysed.
